How do I notify a process of an SQLite database change done in a different process?

The "player" process reads the database and updates a view - in my case it would be a waveform being mixed to the soundcard depending on events stored in the database. An "editor" process is any editor for that database: it changes the database constantly. Now I want the player to reflect the editing changes quickly. I know that SQLite supplies hooks to trace database
